很抱歉我的问题写了我的问题，但我无法真正用一个问题来解释我的问题。

<h1>Aggiungi una persona</h1>

    <div>
        <span><button type="submit">Conferma</button></span>

这是我在Springboot和Thymeleaf中使用的代码来添加一个新人，

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.validation.constraints.Max;
import javax.validation.constraints.Min;
import javax.validation.constraints.NotBlank;
import javax.validation.constraints.NotNull;

@Entity
public class Persona {

   @Id
   @GeneratedValue(strategy = GenerationType.AUTO)
   private Long id;

   @NotBlank
   private String nome;

   @NotBlank
   private String cognome;

   @NotNull
   @Min(0)
   @Max(120)
   private Integer eta;

   public String getNome() {
       return nome;
   }

   public void setNome(String nome) {
       this.nome = nome;
   }

   public String getCognome() {
       return cognome;
   }

   public void setCognome(String cognome) {
       this.cognome = cognome;
   }

   public Integer getEta() {
       return eta;
   }

   public void setEta(Integer eta) {
       this.eta = eta;
   }

   public Long getId() {
       return id;
   }

   @Override
   public boolean equals(Object obj) {
       Persona persona = (Persona)obj;
       return this.nome.equals(persona.nome) && 
               this.cognome.equals(persona.cognome) &&
               this.eta.equals(persona.eta);
   }
}

这是人类的班级。

现在，我想在人类类中添加一个新属性：list＆lt; child＆gt;儿童。每个孩子都有一个名字和姓氏。如何将其添加到我的百里叶代码中？谢谢您的帮助，如果您需要我发布更多的代码，请告诉我

This is the code I'm using in springBoot with thymeleaf to add a new person,

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.validation.constraints.Max;
import javax.validation.constraints.Min;
import javax.validation.constraints.NotBlank;
import javax.validation.constraints.NotNull;

@Entity
public class Persona {

   @Id
   @GeneratedValue(strategy = GenerationType.AUTO)
   private Long id;

   @NotBlank
   private String nome;

   @NotBlank
   private String cognome;

   @NotNull
   @Min(0)
   @Max(120)
   private Integer eta;

   public String getNome() {
       return nome;
   }

   public void setNome(String nome) {
       this.nome = nome;
   }

   public String getCognome() {
       return cognome;
   }

   public void setCognome(String cognome) {
       this.cognome = cognome;
   }

   public Integer getEta() {
       return eta;
   }

   public void setEta(Integer eta) {
       this.eta = eta;
   }

   public Long getId() {
       return id;
   }

   @Override
   public boolean equals(Object obj) {
       Persona persona = (Persona)obj;
       return this.nome.equals(persona.nome) && 
               this.cognome.equals(persona.cognome) &&
               this.eta.equals(persona.eta);
   }
}

And this is the Person class.

Now I want to add a new attribute to the Person class: List<Child> children. Every child has a name and a surname. How do I add it to my thymeleaf code?
Thank you for helping, if you need me to post more of my code, tell me
